<h1>Flot Examples</h1>

<div style="float:left">
<div id="placeholder" style="width:500px;height:300px"></div>
</div>

<div id="miniature" style="float:left;margin-left:20px">
<div id="overview" style="width:166px;height:100px"></div>

<br id="overviewLegend" style="margin-left:10px">

</div>

<p style="clear:left">The selection support makes it easy to
construct flexible zooming schemes. With a few lines of code, the
small overview plot to the right has been connected to the large
plot. Try selecting a rectangle on either of them.</p>
